Bits Bit Name Settings Description Reset Access
7 VIN_UV_WARN_EN2 0x0 RW
0 Default. Disables generation of SMBAlert when the
VIN_UV_WARN bit is set.
1 Generates SMBAlert when the VIN_UV_WARN bit is set.
6 VAUX_OV_WARN_EN2 0x0 RW
0 Default. Disables generation of SMBAlert when the
VAUX_OV_WARN bit is set.
1 Generates SMBAlert when the VAUX_OV_WARN bit is set.
5 VAUX_UV_WARN_EN2 0x0 RW
0 Default. Disables generation of SMBAlert when the
VAUX_UV_WARN bit is set.
1 Generates SMBAlert when the VAUX_UV_WARN bit is set.
4 HS_INLIM_EN2 0x0 RW
0 Default. Disables generation of SMBAlert when the
HS_INLIM_FAU LT bit is set.
1 Generates SMBAlert when the HS_INLIM_FAU LT bit is set.
3 PIN_OP_WARN_EN2 0x0 RW
0 Default. Disables generation of SMBAlert when the
PIN_OP_WARN bit is set.
1 Generates SMBAlert when the PIN_OP_WARN bit is set.
[2:1] GPO2_MODE 0x2 RW
00 GPO2 is configured to generate SMBAlerts.
01 GPO2 can be used a general-purpose digital output pin. The
GPO2_INVERT bit is used to change the output state.
10 Default. GPO2 is configured as a retry fail output.
11 This is digital comparator mode. The output pin now reflects the
live status of the warning or fault bit selected for the output. In
effect, this is a nonlatched SMBAlert.
0 GPO2_INVERT 0x0 RW
0 Default. In GPO mode, the GPO2 pin is active low.
1 In GPO mode, the GPO2 pin is active high.

[11:0] IOUT_WARN2_LIMIT Threshold for the IOUT measurement through the sense resistor,
expressed in ADC codes. This value can be either an undercurrent
or overcurrent, depending on the state of the
IOUT_WARN2_OC_SELECT bit set using the DEVICE_CONFIG
command.

5 OPERATION_CMD_ENABLE Enable operation command. 0x0 RW
0 The OPERATION command is disabled, and the ADM1075 issues a
NACK if the command is received. This setting provides some
protection against a card accidentally turning itself off
1 The OPERATION command is enabled, and the ADM1075
responds to it.
